Can you provide a rationale for the change? Maybe a test?

In #599, for early failures (like an invalid key), the SpherePaths initialization proactively creates all of the .sphere dirs., preventing follow up commands with the correct key, as the sphere dirs are no longer uninitialized. Added a test in noosphere/tests/cli.rs
